Nginx+tomcat cluster +redis (memcache) session sharing!

nginx+tomcat+redissession Shared

The usual way to keep the session:

1 , some agents (such as Nginxip_hash)

1 , using the database to store the session

2 , using cookies to store session

3 , using Redis to store sesssion (Memcache can also)

......

Environment:

192.168.1.220 nginx centos6.6 Port:

Version: 1.9.2

192.168.1.224 tomcata centos6.6 Port: 8080

192.168.1.225 TOMCATB centos6.6 Port: 8090

version: jdk:1.7.0_75 Tomcat: 7.0.54

192.168.1.223 Redis 3.0.5 Port: 6379

Configure session hold and test:

nginx.conf Configuration:

Upstream www.tomcatcluster.com {

Zone MyApp1 64k;

Server 192.168.1.224:8080 weight=1 max_fails=2fail_timeout=30s;

Server 192.168.1.218:8090 weight=1 max_fails=2fail_timeout=30s;

}

server {

Listen default;

server_name www.tomcat.com;

Location/{

Proxy_pass http://www.tomcatcluster.com;

}

}

Tomcata:TOMCATB

Session hold:

Edit Tomcat configuration file Context.xml (both Tomcata and TOMCATB operations)

<Context>

<valve classname= "Com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve"/>

<managerclassname= "Com.orangefunction.tomcat.redissessions.RedisSessionManager"

host= "192.168.1.223" <!--Redis Address --

port= "6379" <!--Redis Ports --

paassword= "Tomcat" <!--Redis Password -

database= "0" <!-- Storage Session Redis Library number--

maxinactiveinterval= <!--Session failure interval (seconds)- -

How do I test session sessions to maintain?

You can see that although the server changes from Tomcata to TOMCATB, the session creation time has not changed, which completes the session sharing.
